Increasing RAM on 32-Bit PC

Users with the appropriate Windows OS can take advantage of potentially all the installed RAM up to a limit of 3 GB on 32-bit PCs. Doing so also requires setting up the appropriate OS boot.ini switch (/3GB) to tell the OS that 3 GB is to be used for application space and only one GB for the OS kernel and related overhead.

64-bit System Requirements

Minimum System Requirements:

Supported processors: AMD Athlon 64, AMD Opteron, Intel Xeon with Intel EM64T support, Intel Pentium 4 with Intel EM64T support Hard Drive Space (for HFSS software): 200 MB

RAM: 2 MB

Recommended Minimum Configuration (for Optimal Performance)

Supported processors: AMD Athlon 64, AMD Opteron, Intel Xeon with Intel EM64T support, Intel Pentium 4 with Intel EM64T support Video card: 128-bit SVGA or PCI Express video card Hard Drive Space (for HFSS software and temporary files): 700 MB

RAM: 8 GB

Increasing RAM on a 32-Bit Windows Vista PC

If you are running the Windows Vista 32-bit Operating System, you can take advantage of potentially all the installed RAM up to a limit of 3GB on 32-bit machines. On Windows Vista, the /3gb switch has been replaced with an option called increaseuserva. You must edit its value using the bcdedit utility.

If you type bcdedit from a Windows command prompt, you will see the current values for the Boot Manager and Boot Loader. If you do not have increaseuserva set, then you will not see this line in the boot loader output.

To set increaseuserva to 3GB:

1. Open a Command Prompt window.

2. Type bcdedit /set increaseuserva 3072 in the Command Prompt window and press Enter.

To delete the increaseuserva setting, which will revert the OS back to 2GB:

1. Open a Command Prompt window.

2. Type bcdedit /deletevalue increaseuserva in the Command Prompt window and press Enter.
